By 2100, a temperature rise of 3.2 degrees celsius is predicted to happen, causing a sea-level rise affecting between 500 million and three billion people, and submerging the megacities situated in the coastal areas. An essential part of living in the future, when the ocean rises up and claims the majority of the earth's land, might be that humans are forced to spend much of their lives in the water. This garment can support that. Functioning like gills it allows humans to survive when sea levels rise up and submerge the earth. Called Amphibio, the two-part 3D-printed accessory prototype consists of a gill and a respiratory mask. It is designed to allow humans to completely breathe underwater. Although it currently doesn't produce enough oxygen to sustain human breathing, it is able to successfully extract oxygen from water, and release carbon dioxide back in – meaning it has the potential to be used for breathing.
